On October 24, Sandy was upgraded to a hurricane, shortly before making landfall in Jamaica. Upon moving further north, Sandy re-entered water and made its second landfall in Cuba during the early morning of October 25 as a Category 2 hurricane. During the late evening of October 25, Sandy weakened to Category 1 strength; in the early hours of October 26, it headed north through the Bahamas.Sandy briefly weakened to a tropical storm in the early morning hours of October 27, then re-strengthened to a Category 1 hurricane later that morning and remained that strength through the evening of October 28. At 11:00 p.m. On October 28, Sandy surpassed Hurricane Igor to become the largest hurricane in Atlantic history, with a maximum gale-force wind diameter of 930 miles (1500 km). Shortly after midnight of October 29, Sandy turned towards north and started to make its expected approach towards the U.S. coast.
